To all whom it may concern:

Be it known that I, LINCOLN Moss, a citizen of the United States, and a resident of the borough of Manhattan, city, county, and State of New York, have invented certain new and usefulv Improvements in Trippers or Deliverers ioLConveying Apparatus, of which the following is a specification accompanied by drawings.

This invention relates to conveying apparatus, but more particularly to the tripper or deliverer for such apparatus. Its objects are to improve upon the construction of tripper for conveyors, to'secure greater efliciency thereof, and especially to provide a form of tripper by means of which the material discharged therefrom can be delivered at a greater distance from the conveying apparatus and from the tripper itself, and thus material can be distributed over a greater area with a single conveyor and a single trippor, than has been possible with the forms of deliverers for conveying apparatus devised heretofore. v

The travel of a tripper is always along the line of the coilveyer, and is, therefore, in a relatively straight line. So far as I amaware, the delivery from all trippers now in use is either directly from the tripper,

or through chutes so arranged that the mziterial dis-,

charges therefrom by gravity. It is impossible or such trippers to distribute the material to any considerable distance from the line oi their travel, so that it is necessary to make use of a plurality of trippors and a plurality of conveyors, or to change the line of travel of the single trippcr, in order to distribute material over aspace of any considerable width. It is frequently necessary, for one reason or another, to distribute 1na terial over a large area, and it is manifestly desirable to accomplish this with a single conveyor and its tripper, and without moving the conveyor so as to change the line 01' travel of the tripper.

A further reasonior delivering material irom a trip per at a distance therefrom, and hence from the conveyor, is that it has been found in practice that the material discharged from the trippe rs now in use is delivered and piles up so close to the conveyor as often to inter' fore with its operation and that of the trippcr.

My improved tripper is adapted to accomplish the Figure 1 is a front end elevation, partly in section.

of apparatus embodying the invention; Fig. 2 is a top plan-view oi the apparatus, partly in section, with some parts omitted; Fig. 3 is a side elevation of the apparatus on a smaller scale; Fig. 4 is a sectional detail view-on the line :cx of Fig. 1; Fig. 5 is a detail plan view, showing the gear drives for the side conveyors and the manner in which those conveyers are universally pivotcd at their inner, tail, or receiving ends; Fig. 6 is a front end elevation, of a form of the inven; tion in which a single, conveyor and a counterweight therefor are rigidly mounted on the tripper or deliverer; Fig. 7 is a front end elevation, and Fig. 8 is a side elevation, both on a smaller scale, of a form of the invention in which a traveling tower furnishes support for the discharge hopper and chutes and the outer ends of the side conveyors.

Referring to Figs. 1 to 6, inclusive, of the drawings, A represents a tripper or delivercr, supported on wheels 15, which travel on rails O. The tripper is supplied with coal, ore, or other material, by belt D (only a portion of which is shown). This belt passes over bend pulleys E and F, and forms an ogee curve, like the letter S, over these pulleys. The material carried by the bolt, whichtravels in the direction indicated by the arrow (Fig. 3), is discharged from the belt in line therewith as it passes over pulley E, and falls into the mouth of hopper G, ,which is rigidly supported and carried on the irame oi the tripper.

As shown in Figs. 1, 2, 3 and 7, hopper G is provided with lonr discharge chutes, I, J, K and L, two of which, i and J, discharge upon the respective side or wing conveyers M and N, while the other two, K and L, afford direct discharges from hopper G to the storage pile or other place in which it is desired to deposit the material.

The inner, rail or receiving ends of side conveyors M and N are universally pivoted on the lower part of the tripper frame, and the outer ends of those conveyers are supported by guys O, the upper ends of which are secured near the top of the tripper frame and a considerable distance apart; Each guy is provided with a turnbuckle I, and by tightening or loosening one.or both of the turnbuckles on the guys of either conveyer, as required, the outer or discharge end of that conveyer may be raised or lowered, 0r swung to the right or left in a horizontal plane. By raising or lowering the discharge ends of these side conveyers the trajectories of the material discharged therefrom may be varied to a considerable extent, while by swinging these conveyors in a horizontal plane it becomes. possible to reach desired, points of discharge which could not be reached if the conveyors were not susceptible of sidewise'swing.

The power for driving side conveyors M and N is derived, through an arrangement of sprockets and gears, from ,pulley F, which is caused to revolve by the passage of belt D over that pulley when the conveyer is in operation. Pulley F is rigidly keyed, or otherwise secured, on its shaft 1, andthis shaft is rcvolubly mounted in bearings. Rigidly secured on the end of shaft 1 is sprocket wheel 2, which is connected by sprocket chain 3 with sprocket wheel 4, rigidly secured on theouter end of shaft 5. This shaft is revolubly mounted in bearings, and has rigidly secured on its inner end bevel gear wheel 6, which meshes with bevel gear 7, rigidly secured on the lower end'of shaft 8. On the upper end of shaft 8 is rigidly secured bevel gear 9, which mcshes with bevel gears 10 and 1], revolubly mounted on the inner ends of their respective shafts l2 and 13.

The rotation of bevel gears l0 and 11 is transferred to their respective shafts when the outer members 14 and 15 of the spiral clutches 18 and 19 are thrown into engagement with their inner members 16 and 17. Outer clutch members l4 and l5 are slidably mounted on their respective shafts, so that they may be thrown either into or out of engagement with the inner clutch members 18 and 19, and thus the transmission or'nontransmission of power from shaft 8 to shafts l2 and 13 is controlled by the two clutches.

Rigidly secured on shafts l3 and 14 are two sprocketwheols numbered respectively 20 and 2|. Sprocket 20 is connected by sprocket chain 22 with sprocket wheel 23, rigidly secured on shaft 24 of driving pulley 25 of side conveyor M, and pulley 25 is rigidly secured on shaft 24 which is rovolubly mounted in its bearings. In a similar manner the revolutions of shaft '13 is transferred to driving pulley 29 of side com-'eyer N by means of sprocket wheel ll, sprocket chain 26, sprocket wheel 27, and shaft 28. The inner ends 28"- of the framing 29" of side convcvcrs M and N are pivoted on the respective shafts 24 and 28, which permits of angular movement of the side conveyors in vertical planes, around those shafts. The bearings of shaft 24 are mounted on upper turntable 30, and the bearings of shaft 28 on lower turntable 31. These turntables turn around a common pivot, formed by hollow shaft 32, in which shaft 6 is supported. Lower turntable 31 forms a complete circle and is supported on plate 33, which rests on the lower timbers of the .tripper frame. Upper turntable 30 is supported on lower turntable 3i, and is cut away so that the two turntables may be turned through a considerable are around shaft 32 in opposite directions, without the supports and gears of the two side conveyers, which are mounted on the respective turntables, fouling each other. Thus provision is made for angular movement of the two side conveyors in a horizontal plane, around shaft 32. As

stated above, the movement of the side conveyors in both the horizontal and vertical planesis controlled by guys O, by means of turnbuckles P, or other similar devices. g

The belts on side conveyors M and N travel in opposite directions, as indicated by the arrows, and dis charge the material received from hopper G through the respective chutes I and .l, over the outer or head pulleys 34 and 35; As stated hereinbefore,-the trajectories of the material discharged from the side conveyers, are susceptible of considerable variation by varying the height of the discharge ends of thoseconveyers. It is also possible by changing the relative sizes of the sprocket wheels or the gears, by means of which power is transmitted from ing pulleys 25 and 29, to vary the speed of travel of the belts of the side conveyors, and thus to vary the trajectories of the material discharged therefrom.

In the type of tripper shown in Fig. 6, a single side conveyor Q is rigidly supported on the lower timbers of the tripper, and on the opposite side of the tripper a counterweight it is similarly supported. The outer ends of the conveyor and the counterweight are supported by guys S. This tripper has only one chute T, which discharges the material upon side conveyor Q. Power is transferred from upper bend pulley E to driving pulley 42 of side conveyor Q by meansof sprocket wheel 36, chain 37, sprocket 38, shaft 39, and bevel pulley F to the drivgears 40 and 41. The belt of the side conveyor travels in the direction of the arrow and discharges the material over head pulley 43.

In the form of tripper shown in Figs. 7 and 8, the hopper and chutes and the inner ends of the side conveyors X and Y are supported on the frame of tower U, which is rigidlyconnected with the tripper and travels on wheels V on track W. Guys Z, which support the outer ends of the side conveyors, are suspended from the upper part ofthe to war frame. This arrangement of the trippcr and traveling tower is designed for use with side conveyors which are so long as to require better support than canbe given by the frame of the trippcr itself. Furthermore, if the hopper and chutes, as well as the side conveyers,are supported on the lower tower framing, the whole apparatus is better balanced,

and the desirable object of removing much of the strainfrom the trippcr itself is accomplished.

It will be seen that this invention contemplates a conveying system provided with a main conveyor, a support, and an'auxiliary or side conveyor, of which there may be more than one, movably connected with the support and havinga' gear wheel at said connection. Means are provided for elevating and again returning the auxiliary conveyor to its normal position, and in order to drive the said auxiliary conveyor, a second gear wheel is provided, with gear wheels engaging said second wheel and the first gear wheel mentioned, at the connection between the auxiliary conveyor and the frame, According to this construction, the main con veyer drives the auxiliary conveyor. The main conveyer it will be seen occupies a plane below that of the auxiliary conveyor wheroon it discharges. Both the main and auxiliary conveyors are connected through the interposition of bevel gear wheels, and it will be seen that there are internualiate bevel gears meshing with said wheels whereby the auxiliary convcyer or conveyors are driven from the main conveyurr, and at. the same time provision is afforded i'or permitting, the free end of the auxiliary conveyor to be raised and lowered. The main conveyer it will be seen is mount ed on a stationary structure but ex tends over and upon the tri i re! while the auxiliar conve ot is mounted substantiall at right angles to the main (:onveyer on the trippcr or traveling structure, and the auxiliary conveyor is driven by the main conveyer, as dcscrilmd.

According to this invention it will be seen that the cross auxiliary conveyer on the tripper is in a plane above the main conveyor, while the tripper itseli at for-(ls movable means for effecting the discharge oi the material from the main conveyer upon the superhuposed auxiliary eonvcyer. There is a. 1)()Wt'lf (t3ill](j(' tion between the main conveycr and ,the tripper or movable discharging means, and it is obvious that the tripper travels with the auxiliary conveycr and affords provision for elevating a portion ot' the main conveycr so that the material. can be discharged therefrom upon the auxiliary convcycr. The tripper or deliverer coustitute's a support, extending over or st raddling the main conveyor, said bridge or tripper carrying elevating devices over which the main conveyor I travels. The auxiliary conveyer overlaps the main eonveyer. and it will be seen that the auxiliaity conveyer furthermore is in a plane above the major portion oi the main conveyor, while the traveling dcliverer or tripper is provided with an inclined portion over which a part oi the main conveyor passes.

Obviously, some features oi this invention may be used Without others, and the invention may be cmbotlied in widely'varyiiu forms.

'ilierefore, without limiting, the invention to the construction shown and described, nor cntnnerat iug equiv alcnts, .l elaim and desire to obtain by iltettcrs latent the i'ollo\ving:

1. in a conveying system, the combination with travel-- in means for discharging material from the conveycr, of an au ary convey r carried by said discharging means and having its free end movable in any direction, for substantially the purposes set. forth.
